Abstract
Analysis of pressure transients in long, single pipelines for water transport has a potential of providing information on hydraulic features such as air/gas pockets,leaks.
Thus the transient measured in a pipeline for sewage water had an oscillation period compatible with the location of a local high point of the pipe profile.
The effect of leaks on transients was studied by means of computer modelling.
It was found that leaks - even small ones of the order of 1 % - interacted significantly with the basic transient.
One effect is a more or less strong attenuation of the pressure oscillations indicating the existence of a leak.
Secondly the leak gives rise to extra pressure wave reflexions the time scale of which can be used for locating the leak.
